Re: [hobbit] log file monitoring

[Rolf Schrittenlocher <Schrittenlocher (at) rz.uni-frankfurt.de>]

Hi Henrik,

thanks for the help and the fast reply! But one more question: Even 
though the client doesn't send new data, is it possible that the server 
displays the old data if you click on the "Full log /var/adm/messages" 
link (or any other log) on the page 
"...bb-hostsvc.sh?HOST=lbsdb&SERVICE=msgs"? Is the data still available 
on the server or is it overwritten each time the client sends something? 
If so, I'd like to modify hobbit in a way that each time a new log 
arrives at the server this is stored somewhere else and we would make it 
available with a link. Could you indicate the files to edit for that 
purpose? Or perhaps, if there is already a command for cutting the 
section code out from a clients message we could trigger that each time 
a client sends something new.

This would be helpful to monitor logs manually. Reason: We often have 
customers demands' to look for special entries in (application)logs 
which don't trigger a yellow or red alarm. These logs are spread all 
over the machines and we hope to get a single point of entry for all 
logs using hobbit.

kind regards
Rolf
